Computer equipment is constantly evolving, increasing its power. However, along with modern power supplies, motherboards, monitors, and other components, it is important to correctly select and purchase a power cable with the appropriate configuration. Despite its simplicity and low price, it can be difficult to find a device of proper quality among the vast number of low-quality products.
For anyone tired of counterfeits, we recommend purchasing a certified power cable from the Discon online store. We offer only original products from leading global manufacturers, confirmed by quality certificates. Our direct supply system from manufacturers’ warehouses allows us to maintain prices at the most affordable level in Ukraine.
Power cable with copper conductor: advantages and disadvantages
Currently, two metals are most widely used worldwide for conductive cores: aluminum and copper. Each has its own characteristics, disadvantages, and advantages that should be known before making a choice. Copper wires were the first used in electrical engineering for telegraphs, telephones, and electric motors. Despite the high cost of the metal, copper is still in high demand because:
- it has high electrical conductivity – second only to silver among all metals;
- with the same cross-section, a copper wire can withstand much higher loads than aluminum with lower voltage losses;
- due to its high plasticity, very thin copper conductors can be produced, adding versatility to the overall cable;
- copper power wires are much more flexible and stronger than aluminum. They do not get damaged from twisting, repeated bending, or kinking;
- the metal practically does not heat up during operation;
- copper’s melting point is over 1000 degrees Celsius, so it will not melt under overload, reducing the risk of fire.
Additionally, copper has high tensile strength and can withstand high voltage with minimal wear. Thanks to its hardness, copper contacts are more reliable, easier to process, and the slowly forming oxides do not prevent electricity flow.
The disadvantages of copper include rarity, expensive extraction, heavier weight (compared to aluminum), and susceptibility to rapid corrosion in humid maritime climates.
How to choose a power cord
The industry produces many types of this product, which differ in thickness, length, material, and other characteristics. Its design should ensure flexibility, safe operation, and prevent kinks. When purchasing a power cord, consider:
- length – this parameter is not strictly standardized. We offer cables from 1 to 3 meters;
- cross-section – selected depending on the device power, but should not be too large to keep the cable flexible. We offer 0.75, 1–2.5 sq. mm products;
- conductor material – copper is considered the highest quality, most reliable, durable, and safe;
- insulation – provides protection, preventing contact between cores (inner) and external factors (outer).
